California’s gray wolf record is enormous in extent and small in substance. Its 371 records touch 46 of the state’s counties, from San Diego’s 75 at the Mexican line to Lassen’s 17 in the far northeast, but the living animal belongs to a narrow corner of that map.

OR7 and the first packs in a century

California’s wolves were gone by the 1920s, and their return began with one famous traveler: a dispersing Oregon wolf known as OR7 crossed into the state in late 2011, the first wild wolf confirmed in California in 87 years. He eventually founded a pack back in Oregon, but others followed his route south, and in 2017 the Lassen pack was confirmed raising pups in the state’s northeast, the first California pack of the modern era. A few packs now hold territories in the Cascade and Modoc country, and Lassen County’s place near the top of the record reflects them.

A big state with a small wolf range

The record’s long southern tail, running through Los Angeles, Riverside, and the desert counties, traces specimens, captive animals, and misread canids rather than wild packs, because California’s verified wild wolves have never left the northeast. Their calendar runs year-round with a midwinter lean, January strongest of all, which fits a territorial animal that breeds in late winter and travels hardest in the cold. Most Californians will never see a wild wolf: the state’s few packs keep to remote forest and give people a wide berth.

Status in California

NatureServe ranks the gray wolf S1, Critically Imperiled, in California, and the species is native to the state. USGS NAS does not list it as nonindigenous here. Globally the gray wolf stands G5, Secure, a worldwide measure that says little about California’s thin and recent return.
